Trust Verisign Class 3 Citrix certificate in Linux Citrix sessions

Citrix Systems make among other things remote access server software which you access with the so-called Citrix Server Client software, downloadable from the installed Citrix server.

This is fine in most instances and most users, where everything works out-of-the-box. When using the Linux versions of the client though, you may get an error message as such:

"You have not chosen to Trust Verisign Class 3 certificate" or something along these lines.

This is the process which will ensure the Verisign Class 3 certificate is trusted:

1) Install Citrix Server ICA client (linuxx86.tar.gz) from the Citrix host
2) Save the Verisign Class 3 Secure Server CA certificate I attach (you may also download this directly from Verisign)
3) Save as/rename it to class3.crt
4) Move this file to your ICAClient/linuxx86/keystore/cacerts folder
5) Try again now, it should work now.

This has been tested with the Kubuntu and openSUSE distros.



Kubuntu xorg.conf: 1680x1050 with NVidia FX series on 22" Samsung Syncmaster 2232BW

Setting a 1680x1050 (widescreen) resolution on Linux is for some reason quite difficult.

Maybe not enough Linux users prefer this resolution for it to be as straightforward to set as for instance 1920x1080 (widescreen) or 1280x1024.

But this is the native resolution of 22 inch monitors, such as the SyncMaster 2232BW by Samsung and having one as such becomes quite a painful experience on too many distros.

The following are taken from the xorg.conf that basically guarantees to get this resolution going. It works on various distros, such as OpenSUSE and Kubuntu. The trick was to remove all other resolutions, forcing this one...

It is geared towards proprietary NVidia FX drivers, so if you do not have one, remove the "Module" and "Driver" sections.

Here are the contents of the /etc/X11/xorg.conf file:
